To all whomA it may concern:

Be it known thatL JEAN CLAUDE MARIE 4.]?Ass1:no1-r,- a citizen of France, residing at Lyon, Rhne, France, have invented new and 5 useful Improvements in Elastic Wheels, of

which the following is a specification.

The present invention relates to a new arrangement applied to the construction of wheels for various vehicles, and has for its bxo ject to avoid the inconveniences arising from the use of pneumatic, tires, which object is atg tained by the construction of ja special form of wheel in which the usual air-tube and indiarubber outer cover are dispensed with, the dex5 sired elasticity being obtained by the employment of an elastic bed between the felly and the axle and avoiding, or at least reducing,

the vibrations and jolts communicated. to the vehicle by the inequalities" of the road upon zo which the wheel runs. Further, the wheel is retained in its field of rotation.

The type of wheel represented on the accompanying drawings is applicable to wheels vfor all kinds of vehicles. The wheel repre- '-7125 vsented issupposed to b e without welght .thereon.- j y f Figure llisan elevation of the wheel with parts reioved. Fig. 2 is a horizontal section drawn on the line A A of Fig. 1.

o One of the disks b and one of the rings a, forming the body of the lwheel and shown in Fig. 2, are supposed to be removed in Fig. 1 in orderA to render visible the-arrangement forming the elastic bed which is contamed in the interior of the rings a a, which latter are fixed one to the othengnd are ca able of sliding against the inner'faces of t e disks b b, forming the 'hubof the wheel and which are keyed on the axle c, as are also the disks d d,

A4o within which radial slots e are formed, those in (Ime disk being placed opposite those in the ot er. I

The elastic bed consists, essentially, of a spring f, formed of a band or ribbon of steel or other metal coiled in a circle around itself. It passes between the clips g, which retain it in 1position without in any way preventing its ee motion, as it is not in any way fixed to these clips, the number of which latter may 5o vary according to requirements. To each of these clips g is connected a small connectingrod h, by means of a pin fi, which is flush with the exterior faces of the clip. Each connecting-rod h carries another pin of suflicient s 5 len th to be capable of cnterin the slots e, wit which it can slide with sllght friction,

being iiush with the exterior faces of the disks d. There are of course as many slots e in each of the disks d as there are connectingrods h in the arrangement. Each of the clips g can only move in arectilinea radial direction in consequence of the trunnions k, which are solid with the clip and are each guided in a groove Z, located on the inner face of the corresponding ring a.

The body in two pieces, constituted by the rings a, is of the form indicated by Fig. 2, and

itsperiphery is constructed to hold in position a leather tire formed of a ring q, fixed to two rings m m, the curved portions n n of which are retained in contact and -gri ped between the two rings a a, which at t is place are brought nearer tovether.

The perfect fixing of the tire, which may be furnished lwith any known protector, is obtained by the employment of nuts and bolts,

such as 0, the stems of which pass through the rin'vs a, and the parts n of the tire passing throug 1 the holes p. (Indicated at Fig. .1.) l

Any arrangement of f elly and tire can be connected to the rings a a; but the arrangement above described is very solid and sufficiently elastic, supposing it to be placed on a wheel furnished with the arrangement of elastic bed, of which the different pieces of mechanism -are above. described, and the operation of which is as follows: When the load is on the wheel, the axle'carries forward ihe pins of the connecting-rods h, which are at the upper pa i' of the wheel. Each of these connecting-rods in its turn carries forward the clip to which it is connected b y means of one ofthe pins i. This clip draws withit the spring f, which passes t hrou gh it. This spring is bent to -an amount determined by each load imposed. It is when one of the clips passes the most elevated position of the curve described by it that its pressure on the spring is the greatest. This spring by its elasticity will gradually return the clip in uestion to its primitive positionepresente on the drawings) in proportion as the load being less normal will weigh less upon it. It will be readily understood that when the wheel receives shocks one or several clips, according to their position at the moment, will act upon the spring,therebyrcducingorpreventingshocks.

This system of wheel presents numerous advantages, among which I would mention, above all, a great i last-icity given to the axle of the wheel, wh ich, receiving llittle or scarcely any vibrations, will offer much less chance of TOO IIO

breakage, and consequently greater' security. I obtain in addition the suppression of the pneumatic tire and of the ordinary springs of vehicles. The construction indicated offers the great advantage of completely protecting the mechanism of the elastic bed Jrom dust and dirt, which might clog it. Further, each ring a is always held between a disk b and a disk d, against which it can slide, and this arrangement gives a very great rigidity to the wheel; but it should be understood that for the construction of all the arrangement devised any suitable materials may be employed, according to the nature of the application. The dimensions ofthe parts and the details of construction may vary, and particularly the size. The thickness ofthe metallic ribbon forming the spring and the number of coils should be determined with relation to the load which the wheel will support.

Having fully described my invention, what I claim isl. In a Wheel for Vehicles, an elastic bed consisting of a metallic spring f concentric with the wheel when the lat-ter is not loaded and att-ached to the axle by an arrangement of connecting-rods 7L, each of which is connected to a clip gthese connecting-rods and clips being capable of moving only in radial directions guided by pins j and trunnions It, the pins y' sliding within slots e formed in two disks d keyed on the shaft, and the trunni ons 7c sliding in grooves Z, formed in the two rings a substantially as herein set forth.

2. In a Wheel for vehicles an elastic bed consisting of a metallic spring f concentric with the wheel when the latter is'not loaded and attached to the axle by an arrangement of connecting-rods h each of which is connected to a clip g these connecting-rods and clips being capable of moving only in radial directions guided by pins y' and trunnions k, the pins y' sliding within slots e formed in two disks d keyed on the shaft, and the trunnions L' sliding in grooves l, formed in the two rings a and means for attaching the external tire which latter has the general form of a T and is held in position by the rings a between which is gripped the part forming the vertical arm ofthe T substantially as herein set forth In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
